Yes, it is important to have their good Christian children be trained in the latest war tactics and art of war. For, the Holy Bible is very clear about the Armageddon War that will come in the Last Days. Christians will need to fight a real physical war using weapons. To win this Great War, Christians need to be trained to fight to win.
Thus, true Christians must send their sons to the US Marines and US Special Forces to be trained to kill and to use the most advanced weapons.
When the War of Armageddon comes, there must be Christians prepared to wage war at the highest skill level and win.
This is very important part of Bible prophecy. Christians who follow the Book of Revelations must prepare for the upcoming War of Armageddon.
Use resources available in the United States, such as signing your children for ROTC programs, US Marine Corp, Police Academy, FBI, CIA, Homeland Security, NSA, etc.
War of Armageddon will be a very sophisticated war with latest weapons and technology. Christians must be prepared for the War of Armageddon that is prophesied in the Bible.
